2017-04-25replace memory representation with map of 1MB pages rather than map of ↵Robert Norton
bytes. This makes loading binaries much quicker but doesn't seem to make a big difference to execution speed.
2017-04-25Don't die if stdin gets closed (e.g. when running unit tests).Robert Norton
2017-04-25support loading more than one raw file as anonymous arguments so that we can ↵Robert Norton
load simboot + kernel.
2017-04-25remove unused function.Robert Norton
2017-04-25Add support for uart terminal. Also add read_bit_reg function for faster and ↵Robert Norton
neater access to registers of single bit.
2017-04-24added register_value_for_regShaked Flur
2017-04-21it turns out zarith has a function for printing big_ints in hex. Remove the ↵Robert Norton
dependency on ocaml uint library by using it.
2017-04-21define some big_int literals in sail_values.ml to avoid lots of calls to ↵Robert Norton
bit_int_of_int. Likely very little performance benefit but slightly more readable.
2017-04-21Revert change to check in type_check.ml.Alasdair Armstrong
2017-04-21Fixes stack overflow in sail caused by list append in type_internal.ml.Alasdair Armstrong
Also makes the check function in type_check tail recursive.
2017-04-21remove unnecessary cast in incrementCP0Count (run every instruction) for ↵Robert Norton
potential speedup.
2017-04-21implement to_vec_big using zarith extract for some speedup.Robert Norton
2017-04-21suppress register field tracing if not enabled (missed in previous commit)Robert Norton
2017-04-21add make variable for setting ocaml compilation options (e.g. set to -p to ↵Robert Norton
enable gprof profiling)
2017-04-20more library optimisation. Implement int_of_bit_array using shift, avoiding ↵Robert Norton
need to use power.
2017-04-20implement vector subrange using Array.sub for approx 10% speedup.Robert Norton
2017-04-20remove unnecessary lemlib include in compile.Robert Norton
2017-04-20work around ocaml shallow embedding problem with matching on big_ints by ↵Robert Norton
restructuing switch as if
2017-04-20add support for cheri128 ocaml shallow embeddingRobert Norton
2017-04-20add brackets around integer literals so that ocaml parses them correctly and ↵Robert Norton
doesn't mistake the - for minus operator
2017-04-20build a single run_embed.native with mips and cheri models linked and choose ↵Robert Norton
between them using a command line switch.
2017-04-20remove unsed code for elf file loading in run_embed.Robert Norton
2017-04-20return zero for uninitialised memory in ocaml shallow embedding model. ↵Robert Norton
Necessary to pass test_cp2_tagmem test. TODO make this configurable.
2017-04-20add support for tagged memory functions in mips_extras_mlRobert Norton
2017-04-20XXX remove pattern match not handled correctly by ocaml embedding.Robert Norton
2017-04-20attempt to optimise performance if not tracing writes.Robert Norton
2017-04-20add missing min and max functions, overriding built-in ocaml ones. Also ↵Robert Norton
neq_range.
2017-04-20add missing KD_nabbrev support in ocaml shallow embedding.Robert Norton
2017-04-20support assert in ocaml shallow embedding.Robert Norton
2017-04-20use mangled field name when accessing record field.Robert Norton
2017-04-20add name to register representation and print it on write.Robert Norton
2017-04-18change to spec. of CLC instruction -- clear tag instead of exception if ↵Robert Norton
permit_load_cap not set.
2017-04-18add workaround for sail shallow embedding problem concerning semantisc of ↵Robert Norton
register reads.
2017-04-18make ocaml embedding of foreach use (now universal) big_ints.Robert Norton
2017-04-18fix definition of mask -- Vregister and VvectorR were swapped.Robert Norton
2017-04-18Implement return using an exception caught in the function body. Polymorphic ↵Robert Norton
exceptions are not permitted so a local mutable variable, ret, is used in ocaml to store the return value. This avoids having to define a new exception type for each function. Ocaml infers the type of the option when it is assigned at the return site.
2017-04-18remove debug print.Robert Norton
2017-04-18Generate runtime error for L_undef. Existing code was broken except for type ↵Robert Norton
bit (specifically it caused generated ocaml to fail to type check for an undef number.
2017-04-18added transactional memory supportShaked Flur
2017-04-07fix error in generated ocaml where writing single bit of register was not ↵Robert Norton
taking account of register direction.
2017-04-07implement quot and mod with truncation towards zero which is not the ocaml ↵Robert Norton
way but standard for C and most hw.
2017-04-07simplify xor using ocaml <> operator which also has the advantage of being ↵Robert Norton
more correct

2017-04-06typesetting tt vs non-ttPeter Sewell
2017-04-06use set_register when writing element of vector of registers to avoid ↵Robert Norton
accidentally replacing Vregister with Vvalue or Vregister... Seems to work for MIPS but not sure if might encounter vector of something other than bit or register. A more specific value type would have made this a compile-time error rather than run-time.
2017-04-06add support for address translation and exit handling in mips ocaml shallow ↵Robert Norton
embedding test setup.
